This thesis describes an aspect of the operational and functional implementation of the CORES instrument, an electronion spectrograph to be flown aboard the Russian Obstanovka Experiment Complex mission to the ISS in 2008. For the phenomenon under investigation, wave-particle interactions in space plasma, CORES is ideally suited as it can accept a very wide band of energies simultaneously and at the same time have 3600 field-of-view. This instrument includes a novel delay-baSed particle readout system, . developed specifically for this application. A reconfigurable device (FPGA) lies at the heart of the instrument, and this has been taken fully advantage of to achieve the necessary functionality. As such this thesis mostly focuses on the configuration of this device, which allows for the multi-channel particle capturing, as well as defining the processing abilities of the instrument. These include a number of novel functions implemented in hardware for spectral analysis of the recorded particle events, such as a parallel version of se~ond order correlation, a parallel version of the I-bit autocorrelation function, etc. Furthermore, an innovative tool for on-board telemetry filtering is also presented, namely the on-board calculation of the information content of the collected measurements. This thesis also offers a technical view of CORES, presenting its capabilities based on its hardware structure.
